They could do 15mm squares?
Or even better, Xray die shots of some apple customs?

I think the idea of resin is to stop the irregularly-shaped logic board from wobbling around, or from being anything but perfectly level as the milling machine slowly removes each layer. Honestly, with every component removed from the board (thus making it flat), this may not be necessary. As far as I know, somehow, milling machines should be able to clamp to a thin rectangle pretty well. They should also be precise enough to remove thousandths of an inch from the PCB, too.@Trash80toHP_Mini's milling idea sounds promising and do-able to me. I wish I understood the resin mold part though.
YES. The Classic BBU i desoldered works fine in the SE board that @cheesestraws loaned me.Is the BBU compatible with the SE one ?

I understood the purpose of the resin, but not being a mechanical engineer person didn't understand how one would accomplish it. Thanks @Trash80toHP_Mini for explaining one possible way to do it. Sounds like it might be more suited to a CNC mill (for the leveling part) than a manual mill like I had in my head.
1 oz copper is 0.035 mm thick... that's some mighty precise leveling to pull off.
@Kai Robinson - Having experienced similar loss of extensive and invaluable work myself elsewhere, I totally understand the frustration, and the wish to find a more stable platform to share your efforts.
But for one tiny reason, I hope you reconsider. It's this: The more the ongoing efforts to support vintage systems and their owners fragments into ever-more discrete places, the harder it is for us to find out what is even possible, let alone available.
I joined here earlier this year precisely because it contained your work (and that of others) which promised the possibility of putting old Macs I own back into practical and valuable use. Without finding this very thread in March this year, I wouldn't have even known there was a project to re-engineer a board for my Classic, so I wouldn't have known to go looking anywhere else to find one.
Refusing to continue updating your work here is your right, and would be understandable, but after a time it would drop out of visibility, and once again, the knowledge that someone, somewhere, is doing this great work would be lost again to people like me who won't know to look for you.
In your shoes, I'd be mad as hell, but even so, I 'd be inclined to think that taking my talent elsewhere would maybe be punishing the wrong people.
But, thanks anyway, for demonstrating that the impossible isn't!
This is like deciding to stop working on cars because you lost the maintenance receipts... Can't say I understand but do whatever you feel is best man.I think I'm gonna just quit developing anything, at least for now. All projects are cancelled.
Any enjoyment that I got from this hobby has sailed out the window now.
I wasn't aware that others were entitled to my work. If I release any of it, it'll be at a time I choose, and if I choose to finish it. Only once finished will I consider posting it.Well --
I do understand the frustration of having the rug pulled out from under you; so if you feel that's what you want to do, OK...
... but before you quit completely, can you make sure that all your project files (including the source for any custom tools you may have built) are up somewhere like github, so that others may follow in your footsteps, so-to-speak?
Hi Andy.
I think I'm gonna just quit developing anything, at least for now. All projects are cancelled.

Maybe the one good thing to come from this is that people will know that these things are possible.
Thanks for your kind words.
